Emergency unlocking system for the trunk of a motor vehicle
First Claim
1. An emergency unlocking system for a motor vehicle trunk comprising:
- a trunk lock, comprising at least one lock latch and one interacting locking part,a catch means which limits a trunk opening motion and comprises a catch hook which can be actuated from outside the trunk and an interacting catch hook engagement element for canceling the motion limitation, andan emergency unlocking means located in the trunk adapted to be actuated by a person inside the trunk, and acts to open the trunk lock and to release the catch means when actuated,wherein the actions applied by the emergency unlocking means to the trunk lock and the catch means are decoupled from one another.

Abstract
This invention relates to an emergency unlocking system for a motor vehicle trunk (2), with a trunk lock (6) which comprises at least one lock latch (7) and an interacting locking part (8), with a catch means (14) which limits the trunk opening motion and which comprises a catch hook (15) which can be actuated from outside the trunk (2) and an interacting catch hook engagement element (16) for canceling the motion limitation, and with an emergency unlocking means (20) which is located in the trunk (2) and which acts to open the trunk lock (6) and to release the catch means (14) when actuated. In order to offer an increased safety standard with a simple structure and to meet safety stipulations with respect to the speed-dependent allowability of emergency unlocking, the actions applied by the emergency unlocking means (20) to the trunk lock (6) and the catch means (14) are decoupled from one another.

13. A method of preventing unlocking of a motor vehicle trunk comprising:
-
measuring a speed of the vehicle; preventing opening of an unlocking system when the speed of the vehicle is greater than a reference speed, the unlocking system comprising; a trunk lock comprising a lock latch and an interacting part, and an emergency unlocking means located in the trunk to be actuated by a person inside the trunk, wherein activation of the emergency locking means acts to disengage the trunk lock when actuated, and the speed of the vehicle is less than the reference speed wherein the unlocking system further comprises a catch means and an interacting catch hook engagement, decoupled from the trunk lock, for limiting movement of the trunk when the trunk lock is disengaged. - View Dependent Claims (14, 15)

16. An emergency unlocking system for a motor vehicle trunk comprising:
-
a trunk lock, comprising a lock latch and an interacting part; an open-motion limiting means, comprising a catch hook and an interacting catch hook element, wherein the open-motion limiting means is decoupled from the trunk lock; an unlocking means for unlocking the trunk lock; and a speed-dependent actuating element, positioned to prohibit disengagement of the trunk lock and/or the open-motion limiting means in response to a speed detected for the vehicle being greater than a reference speed.
